- dow Construction, of which the following is with which the same can be madefromsheet,

"" a in which are formed the channels or runa specification.

his invention relates to improvements made in sheet-metal window-frame and sash, and is applicablemore articularly to win- 'dow-construction wherem-the sashes are arrangedor adapted to swing as well as to slide in. the frame.

' The invention has forits object the production of a sheet-metal window-"frame having several improved features and several important advantages over other construetions, eslpecially wit regard to the few parts or mem ers, and the cheapnes's and facility metal and put together.

.A. further object is the production of a window-frame in which the sashes are readily hung or arranged so as to swing on pivots, or to slide up and down, according-as it may be desired to raise or lower the sash perpendicu larl or to swing in the frame.

0 such ends and objects chiefly, the invention comprises certain novel construction and combination of sheet metal parts or members dproducing a sheet-metal windowframe an casing having separate runways for the up er and lower sashes, slidable shoes carrying t e sashes, and means pivotally attaching the sashes to the shoes, all as hereinafter more fully described and pointed out in the claims at the end of the specification.

In the accompanying drawings which illustrate the appllcatlon of the said improvements to the construction of a frame with swinging and sliding sashes, of a sheet-metal window.

Figure 1 represents in front elevation .a window construction embodying thesaid improvements, with upper and lower sashes pivotally hung to swing horizontally, and

also adapted to slide up and down,-the window-casing being partlybr'oken away at one side to disclose the )arts within. Fig. 2 is a transverse sectional -view vertically through the frame, and the upper and lower sashes. Fig. 3 is a sectional-view on an enlarged scale of a portion of the frame or casing at one side and the vertical member of the sash adjacent to the casing at that side; the section being taken horizontally through the upright members of the casingand sash. Fig. i is a similar horizontal section, taken through the frame and the up or sash at about the line ac-y Figs. 1-2, ut on an enlarged scale. Fig. 5 is a detail view, in perspective, of parts composing the frame, the shoe and the upright member of the sash which is attached to and carried by the shoe on that side. Fig. 6 is a detail partly in section of one of the hinges or pivots on which the sash is hung in the frame.

In the several figures of the drawings the various parts or members are designated as the stationary frame a, the sliding-shoes l)c, the stiles or upright members m; the rails or horizontal members 77, of the sashes; and the bin es g on which the sashes are hung.

'ith the view of reducing the number of parts and the labor necessaril involved in fastening the'parts together, t e fronteplate ways for the upper and lower sashes, D-E,- and the outer and inner vertical sides of the stationary casin are made in one piece, united at the bacii by the back-plate 5. But Where it may be necessary or more convenient to use smaller sheets of metal, the front and the sides can readily be formed of so arate plates joined together byinterlockmg their edges in the same manner as the back plate is secured to the sides 4.

The frame to carry an upper and a. lower sash will thus be formed with two runways extending from top to bottom, on both sides of the frame. But Where a single swinging and sliding sash is employed, therewill obviously be but side, and the frame can be formed accordingly. Following the construction of sinnlar swinging and sliding windows, each sash is hinged or pivoted to sliding bars or members usually termed the shoes; the same being a bar or strip fitted to slide easily up and down and carrying the sash, which ishinged or pivoted to the shoe at each side; of some kind are interposed between the s 0e and the frame, or between the stile orsidebar of the sash and the shoe for the mrposc of holding the sash in place and pro ucing a tight-joint between the shoe and the sash.

In my present improvements each shoeis formed of sheet-metal and preferably of a single stri or piece, by bending a strip of metal of tlie required length and width into one runway required on ea ch in the runway between the stops of the frame Sprinsp narrow space between each adapted, however,

the shape seen in. Figs. 3, 4 and 5 the sides 6 being bent back parallel with each other, and the front face 7 made of curved shape in cross-section, corresponding to the curvature of the stile m of the sash.

Narrow grooves or recesses 8 in the channel to receive and confine the sides 6 of the .shoe are formed by fastening against the back or bottom wall of the channel a strip 10 having standing sides 12'at rightanglesto or parallel with the sides of the channel. This strip is riveted to the hack ol the channel, and is of less width than the channel, so as to leave a V standing-side 9 and the adjacent side of the channel to re ceive the shoe. The recesses before more tioned are of proper depth to retain. the shoe in place against latcral play, and oi proper Witltll to confine the shoe in the vertical or sliding; movement. This construction at lords a simple and clliciont means oi conlining and guidingthe shoe in the frame.

The sash represented in the drawings in connection with the above described con- SULU'LIOL oi metal lFttIllO and shoe contains seven 31 novel features which are reserved for a separate application. The same are well to he used in connection with the pr ascnt invcntion in the nodnction of a fire-prml" swinging and sliding window, especially with regard to the feature of securing a close Weather tight-joint at the s des hetweenthc sho s and the stiles of the sash, and to the feature ol placing the pivots on the outside where they are readily accessible Withoht taking the frame apart or removing the sashes.

A detailed description oi the manner of constructing the metal sash and of hanging it in the frame is omitted in this specification, as the novl features thereof are not included in the resent im'cntioi'i, which is not neces sar"y cont-nod or restricted to the use of the particular construction of metal sash herein Shown.

.The pivots f--g at the sides of the sash are provided with knuckles 14 secured to the outside of each uprignt bar, and are fastened blocks 15, fixed on the shoes, sotlzat the pintles 16 are located on the outside Where they arc casily reached, instead of being on the 1nside of the l'ramc. This arrangement has the further advantage of removing the pivots and their bearings iron the inside of I the'shoes out of the Way oi the sprin p, and

. of reducing the dimensions in depth of the shoe and the channel or run-way on the frame. Having thus described lily-invention, What I claim new and. (.lGShB to secure by Letters limited lateral play therein,

P 'ent is:'

a n1etalht2-w1ndow. a trains l. avinga sages-7 front'plate provided with a channel with standing sides, a slida-ble shoe formed of sheet metal and fitted to slide between the standing-sides of the channel, a stationary strip of less width than the. channel secured to t 1e hack thereof and having sides standin with the sides oif'the channel, sai
